Description
Technical field
The present invention relates to a kind of automobile liquid component technology field, particularly relate to a kind of auto automatic adjusting arm.
Background technique
Automatic reglation arm for braking gap, also claims " automatic clearance adjuster " or " automatic adjusting arm ".Automatic adjusting arm has been mature technology abroad, is widely used, and in recent years, the lorry in the area such as Europe, America, passenger vehicle and trailer MANUFACTURER it can be used as the standard configuration of car load all.The function of automatic adjusting arm should be that accurately record to wear and tear the gap increasing amount caused due to friction facing, and accurately braking gap is adjusted to normal operating range.
Adjust the angle stroke of arm during braking and can be divided into three parts: 1, clearance angle, corresponding to the normal clearance of brake drum and friction facing; 2, excess clearance angle, corresponds to the gap increased because of friction facing wearing and tearing; 3, elastic angle, corresponds to by the elasticity caused when brake drum, friction facing and brake cylinder and braking system power transmission.The elastic angle in the stroke of angle should be avoided when gap adjusts automatically as far as possible.If do not distinguish excess clearance angle and elastic angle, compensated at any time without exception, adjustment will be caused excessive, so that cause " dawdling " even " locking ".When starting to brake, adjustment arm straps moving cam axle turns over clearance angle and excess clearance angle, and the wearing and tearing of accurately record generation.Now cam angle stroke is in interstitial area, and the feature of interstitial area is that braking moment change is little.When continuing brake, cam angle stroke enters elastic deformation area, and braking moment sharply rises, until car stops.Unclamp pedal, brake backhaul, braking moment declines, and cam angle stroke gets back to interstitial area.Automatic adjusting arm is according to the excess gap of record during brake, and internal adjustment mechanism drives camshaft to turn over several angle by worm gear, thus completes and once adjust.
Current existing auto automatic adjusting arm complex structure, install inconvenient, easily produce wearing and tearing in using process, working life is shorter.
Summary of the invention
